With 707 horsepower, Dodge Challenger Hellcat out-roars all muscle cars

It’s been a huge car industry secret for most of 2014: how much power will the new supercharged 6.2-liter “Hellcat” V-8 in the 2015 Challenger SRT produce? Today, Dodge reveled the answer: 707 hp.

That’s, um, a lot. The massive engine also makes some serious torque, to the tune of 650 lb-ft, which is enough to turn its massive rear tires into pools of molten rubber faster than you can say “bad kitty!” According to Dodge, this makes the Challenger Hellcat the most powerful Challenger ever, Dodge's most powerful V-8 ever, and the most powerful muscle car ever. (So you don’t have to look it up, Ford’s previous-generation lighter, smaller Mustang GT500 currently boasts a huge 662 hp and 631 lb-ft of torque, while the Chevrolet Camaro ZL1 makes a comparatively wimpy 580 hp and 580 lb-ft of torque. Yep, they’ve been served.)

Gotta make sure you have the right key, however. The Hellcat engine comes standard with two key fobs, red and black. You’ll want the red one, as it is the only one that unlocks the full 707 hp and torque; the black key fob limits the engine’s output to “just” 500 hp. The mean kitty’s partner in crime is a new eight-speed automatic transmission with manual shift control, of course. A full raft of hero-making track apps also comes as part of the SRT Hellcat package.

The engine debuts later this year in the 2015 Challenger, which dons mildly refreshed headlamp, grille, and taillamp designs and as well as an all-new interior, which Dodge says is inspired by the classic 1971 Challenger. Watch this space for our first drive of the Hellcat and the rest of the refreshed Challenger litter in coming weeks.
